Description

Octanoic-D15 Acid CAS NO 69974-55-6 is a fully deuterated isotopologue of octanoic acid, where all fifteen hydrogen atoms are replaced by deuterium. This high isotopic purity makes it an indispensable internal standard and tracer in advanced analytical chemistry and metabolic research. It is primarily required by pharmaceutical R&D laboratories, academic research institutions, and analytical service providers for applications in mass spectrometry, NMR spectroscopy, and pharmacokinetic studies.

Application

• Quantitative Mass Spectrometry (MS): Serves as a critical internal standard for the accurate quantification of octanoic acid and related metabolites in complex biological matrices like plasma, serum, and tissue homogenates.
• Nuclear Magnetic Resonance (NMR) Spectroscopy: Used as a deuterated solvent or a non-interfering tracer in mechanistic studies and structural elucidation to avoid signal overlap from protonated species.
• Metabolic Pathway Tracing: Enables detailed investigation of fatty acid metabolism, β-oxidation cycles, and energy production pathways in live cells and model organisms.
• Pharmaceutical Drug Development: Employed in ADME (Absorption, Distribution, Metabolism, Excretion) studies to track the fate of drug candidates and their metabolites.
• Stable Isotope Labeling: Acts as a building block for the synthesis of more complex, labeled compounds for use in various biochemical and diagnostic assays.
• Quality Control & Method Validation: Essential for developing and validating robust, regulatory-compliant analytical methods in GLP (Good Laboratory Practice) and GMP environments.
